Sport fishing methods vary according to the area being fished, the species being targeted, the personal strategies of the angler, and the resources available, ranging from the aristocratic art of fly fishing invented (?) in Great Britain, to the high-tech, incredibly expensive methods used to chase marlin and tuna. However, in virtually every case, the fishing is done with rod and reel rather than with nets or other aids.
In the past, sport fishers, even if they did not eat their captures, almost always killed them to bring them to shore for weighing. However, pressure from outside combined with genuine concern about fish stocks have seen many sport fishers releasing their captures alive, usually after fitting them with identifying tags and recording their details so as to aid fisheries research (known as tag-and-release).
Sport fishing competitions give competitors (individuals if the fishing occurs from land, usually teams where conducted from boats) a specified time and area to where they are to catch fish from. Scores are awarded for each fish caught, the points depending on the fish's weight and species, and then divided by the strength of the fishing line used (so catching fish on thinner, weaker line scores additional points). In tag-and-release competition a flat score per fish, divided by the line strength, is awarded for each species caught.
